I love PortableFirefox and use it heavily.
I was glad to see the new release.
I ran the extractor setup from this Web site, and coped my 1.0.2 \profile folder from my flash drive to the new Data\profile folder. I updated my extensions and everything ran fine.
Then I copied the FirefoxPortable folder back to my flash drive (an A-data PD2-1G0) and tried running FirefoxPortable. The splash screen appears but nothign happened. I waited 5 minutes. Nothing happened.
Firefox.exe is running, but the program never loads. I killed firefox.exe in task manager. I tried again, and it loaded, but in safe mode -no extensions, no themes.
The copy of FirefoxPortable on my desktop works fine.
